Definitions

  • the invention is based on a high-performance connector system according to the preamble of independent claim 1.
  • Such high-performance connector systems are required to transmit electrical energy.
  • comparable high-performance connector systems are used in the areas of electric rail transport, wind turbines or heavy work machines.
  • such high-performance connector systems are used in the area of large electric motors, electric converters or electric transformers.
  • DE 2928 727 A1 discloses a cable termination for medium-voltage and high-voltage cables, with a deflector serving for field control, wherein a test electrode which at least partially encompasses the longitudinal axis defined by the deflector and is insulated from the cable core and the deflector, which is at least partially arranged in an area not shielded from the outside by the deflector and from which a connecting line is led to the outside of the termination.
  • a disadvantage of such cable terminations is the lack of transmission capability of electromagnetic shielding. Although electromagnetic fields can be dispersed, this can still have a significant negative impact on electrical and electronic devices. In particular, the state of the art lacks solutions for the transmission capability of particularly high electromagnetic shielding, for example in the range of 30A to 50A and recently increasingly required shielding of greater than or equal to 100A.
  • German Patent and Trademark Office has searched the following prior art in the priority application for the present application: DE 102009 016 340 A1, DE 735 551 A, DE 10 32 813 A, US 2022 / 0 128 182 A1 and CN 2 05 282 768 U.
  • the object of the invention is to offer a high-performance connector system with improved and secure shield transmission, which is easy to assemble and maintain and offers helpful protection against faulty plugging processes.
  • the object is achieved according to the invention by a high-performance connector system, consisting of a connector and a mating connector.
  • the connector has a connector housing, a first insulating body, at least one first contact holding device, at least one first high-performance contact, at least one first cable fastening and a connector flange.
  • the connector housing also has a first stop element, at least one first coding unit and at least one first electrical protection device.
  • the mating connector has a mating connector housing, a second insulating body, at least one second contact holding device, at least one second high-performance contact, a second Cable fastening and a mating connector flange.
  • the mating connector housing also has a second stop element, a second coding unit and a second electrical protection device.
  • the connector housing and the mating connector housing each have contact shapes that correspond to one another in the plugging direction, a first contact shape and a second contact shape, which are in an electrically conductive connection from the connector flange to the mating connector flange after a fixing process.
  • a “high-performance connector system” is a connector system that is capable of transmitting currents of over 100 amperes, preferably over 400 amperes, ideally over 600 amperes and especially currents of over 800 amperes.
  • contact holding device is to be understood as a component which is designed to be introduced into a connector housing and/or a mating connector housing in order to fasten a first high-performance contact and/or a second high-performance contact in a desired position.
  • a contact holding device is cleverly introduced into the first insulating body and/or the second insulating body in order to ensure protective insulation of the high-performance connector system in this way.
  • the term “coding unit” is to be understood as a device which enables a user to protect the high-performance connector system against incorrectly combining a connector with a mating connector which are not intended to be plugged together.
  • protective device refers to a device which is preferably arranged on the connector housing and/or the mating connector housing and enables the transmission of a protective earth, a ground line and/or an electromagnetic shield.
  • contact form refers to a molded formation on the plug-side end of the connector housing and/or the mating connector housing. These contact forms are designed to correspond to one another, so that the connector housing and the mating connector housing are connected in a form-fitting manner. This form-fitting connection is preferably secured by a frictional connection of the mounting flange, i.e. the connector flange with the mating connector flange.
  • the connector housing and the mating connector housing are made of electrically conductive material, with either identical materials or different materials being used to manufacture the housings, i.e. the connector housing and the mating connector housing.
  • This embodiment enables, for example, the use of a more robust mating connector housing, which is therefore particularly suitable for use as an attachment housing for attachment to a housing wall or a device wall.
  • the first contact form and the second contact form are designed to transmit an electromagnetic shield from at least one first conductor with shielding element, which is connected to the plug connector, to at least one second conductor with shielding element, which is connected to the mating plug connector.
  • a contact fuse is understood to mean a component that is able to maintain an electrically conductive connection even in the event of vibration or other movements.
  • Other contact fuses are conceivable and can be used advantageously.
  • a particularly safe embodiment provides for the first protective device to be designed to accommodate a first electrically conductive element and the second protective device to be designed to accommodate a second electrically conductive element.
  • the first electrically conductive element and the second electrically conductive element are different from the first conductor and the second conductor.
  • the mating connector is designed as a mounting housing for attachment to a housing wall or to a device wall.
  • the electrically conductive elements used are not directly connected to the first conductor or the second conductor.
  • the first electrical conductor is connected indirectly, i.e. via the connector housing, to the electromagnetic
  • the second electrical conductor is connected indirectly, i.e. via the mating connector housing, to the electromagnetic shielding element of a second conductor.
  • the electrically conductive elements are primarily cables, copper strips, aluminum strips or similar advantageous components. Other electrical conductors are conceivable and can be used advantageously.
  • the first electrically conductive element and/or the second electrically conductive element is electrically conductively connected to a housing wall or a device wall.
  • the first electrically conductive element on the housing wall or the device wall may be electrically conductively connected to the second electrically conductive element.
  • a first electrically conductive element can be identical to the second electrically conductive element, so that an electrically conductive element connects the connector housing to the mating connector housing, so that the electrically conductive element creates a connection between the shield elements of the first conductor and the second conductor in addition to the corresponding contact shapes of the connector and the mating connector. This additional connection can therefore be used for redundancy or to reinforce the shield transmission capability of the connector to the mating connector.
  • the mating connector flange is designed to accommodate at least one first fastening element for connection to the connector and is also provided to accommodate at least one second fastening element for connection to the device wall or the housing wall.
  • the mating connector can be releasably fixed using the first fastening element.
  • a mating connector designed as a panel housing can therefore be fixed to a device wall or housing wall using fastening elements, while the connector is fixed to the mating connector flange, which is preferably already attached to a device wall or housing wall, using fastening elements. Screws, quick-lock pins, various types of rivets, combinations or various alternatives are easily suitable as fastening elements.
  • a useful embodiment provides that the first contact holding device holds the first high-performance contact in the first insulating body of the connector housing in a rust-proof and detachable manner.
  • the second contact holding device holds the second high-performance contact in the second insulating body of the mating connector housing in a rust-proof and detachable manner.
  • the contact holding device sometimes referred to as contact holding plates or contact holding sleeves, are cleverly provided as essentially hollow-cylindrical sleeves with end regions that taper conically on the plug side.
  • the conically tapered end region is provided with recesses aligned along the length, which allow the contact holding device to initially expand when the respective high-performance contact is inserted so that the high-performance contact can be pushed into the housing or into the insulating body up to the intended position. As soon as the high-performance contact has passed the end region of the contact holding device, the expanded conical end region springs back and thus fixes the high-performance contact.
  • the connector has a first insulating element and the mating connector has a second insulating element, the insulating elements with the corresponding insulating bodies forming a contact protection which at least prevents or at least makes it difficult to introduce a standard finger into a first contact area and a second contact area.
  • Both the first insulating element and the second insulating element can be pressed on, glued, clamped or molded, for example by means of a casting process, in particular by means of an injection molding process.
  • the first high-performance contact and the second high-performance contact each have at least one contact securing device, which improves or at least essentially maintains the contacting of the high-performance contacts when they are plugged together in the event of vibration and/or other stress.
  • Means such as the spiral springs, bal-seal springs, contact strips, contact disks and/or contact rings known in the prior art are suitable for this purpose, as is the case for contact securing in the area of the first contact form and the second contact form.
  • Other contact securing devices are also conceivable here and can be used advantageously.
  • the first high-performance contact has a first basically hollow-cylindrical contact region, wherein within the hollow-cylindrical shape a contact pin is formed basically along the central axis of the high-performance contact, which ends with a first insulating element on the plug-in side and wherein within the first hollow-cylindrical contact region at least one recess is provided, which is designed to accommodate at least one contact securing device.
  • the second high-performance contact has a second basically hollow-cylindrical contact region, wherein at least one recess is provided within the hollow-cylindrical shape, which is designed to accommodate at least one contact lock and wherein the contact region of the second high-performance contact can be brought into engagement with the contact region of the first high-performance contact of the connector, so that the second contact region accommodates the contact pin substantially within the first contact region.
